The working principle of the using method of the application is as follows:

when the device walks in a field, the wheels 1 rotate to enable soil in the field to generate wider and deeper tracks, at the moment, the rear plate 3 carries out a scraping operation on uneven ground, the uneven ground rubs the scraping strip 31, the scraping strip 31 rotates around the fixed rod, when one edge of the scraping strip 31 rotates to the extrusion bottom bag 32, the bottom bag 32 is effectively caused to be vertically compressed, liquid in the bottom bag 32 is filled into the top bag 34 through the air pipe 33, the top bag 34 is transversely expanded, the two front plates 4 are driven to move in opposite directions, the front plates 4 effectively scoop up soil blocks stacked on two sides of the tracks in the middle moving process, and throw the soil blocks to the track position, when the edge of the scraping strip 31 rotates to the extrusion bottom bag 32, the bottom bag 32 is effectively caused to be vertically expanded, the liquid in the top bag 34 is returned to the bottom bag 32, the top bag 34 is further driven to be transversely compressed, the two front plates 4 are driven to move in opposite directions, the soil blocks are effectively turned, the soil blocks are fully dispersed, the soil blocks are prevented from being fully dispersed by the front plates 4, and the soil blocks are prevented from being dispersed and the soil blocks from being scattered by the left side of the device to the front plate 3 and the soil is completely dispersed in the middle by the track, and the soil is completely dispersed by the soil blocks on the front plate, and the soil is completely dispersed by the front and the soil blocks after the soil is completely dispersed by the front and the soil blocks on the front and the soil after the soil is completely is filled by the soil;

when the two front plates 4 move in opposite directions or back to back, the front plates 4 drive the moving parts 5 to move in the same direction, so that soil generated by rotation of the wheels 1 at the bottom end of the mud guard 2 is effectively cleaned, when the moving parts 5 move towards the two sides of the mud guard 2, the moving parts 5 overcome the thrust of limiting springs and press the connecting parts 7 to bend, so that the connecting parts 7 can collide and clean the soil scraped by the moving parts 5, the cleaning degree of the bottom end of the mud guard 2 is effectively improved, when the moving parts 5 move towards the middle of the mud guard 2, the thrust of the limiting springs effectively pushes the moving parts 5 to move, preparation is made for continuously cleaning the mud guard 2 by the following moving parts 5, in sum, cleaning of the mud guard 2 can not only prevent excessive soil from affecting normal rotation of the wheels 1, but also can provide soil block supplement for wheel tracks, further ensure that the tracks are timely leveled, and further do not affect farmland operation in later stages;

when the two front plates 4 move oppositely, firstly the movable rod 41 moves and drives the fixed rings 81 to rotate and move in the transverse holes together, so that the protrusions of the fixed rings 81 rotate from the bottom ends of the transverse holes to the top ends of the transverse holes, at the moment, the turning plate 9 is pulled by the pull ropes 91 to be lifted up in a rotating mode, then the fixed rings 81 are blocked by the transverse holes and cannot rotate, so that the movable rod 41 automatically rotates under the action of the fixed rings 81, in the process, the front plates can be transited to the other side of a soil pile on the premise that the front plates do not touch the soil pile due to the lifting of the turning plate 9, and the front plates 4 are effectively prevented from being in a vertical state to push soil blocks to move outwards and cannot effectively fill wheel tracks;

when the two front plates 4 move in opposite directions, firstly, the movable rod 41 moves and drives the fixed rings 81 to rotate and move in the transverse holes together, so that the protrusions of the fixed rings 81 rotate from the top ends of the transverse holes to the bottom ends of the transverse holes, at the moment, the turning plate 9 is pulled by the pull ropes 91 to rotate and fall down, then the fixed rings 81 are blocked by the transverse holes and cannot rotate, so that the movable rod 41 automatically rotates under the action of the fixed rings 81, in the process, the front plates can touch a soil pile due to the falling of the turning plate 9, the front plates 4 are effectively promoted to be in a vertical state to push soil blocks to turn towards the middle of a track, and further effective filling of the track is realized;

in the process of the opposite and backward movement of the two front plates 4, one movable rod 41 is influenced by the corresponding fixed ring 81 to perform self-rotation, so that the movable rod 41 drives the movable piece 42 to cut down hard soil blocks, the soil blocks can be ensured to be broken into small soil blocks and filled in the track positions, and the arrangement of the movable rod 41 and the movable piece 42 further improves the land uniformity effect after filling.
